I've been pulling my hair out for a week now over this. Can't get it to work properly.

We have a remote building connected to the main office through a Telus Fibre WAN (Layer 3) using cisco switches the line carries both data and VOIP traffic. . In addition there is a wireless canopy that is used as a backup on the 172.16.140.0 subnet. We recently switched to this new fibre service from a layer 2 service and we are having a few issues. Iíll start by outlining the setup.

Now here is the issue. The remote office PC's connect to the servers (vlan 400) just fine through the 10.13.11.252 to 192.168.0.252 route. But the IP phones always route through the wireless canopy. They need to reach the voip servers on vlan 71 through fibre, not wireless. In addition, the servers can reach a NAS (remote backup)located on the 10.13.11.0 remote office vlan 11, but the main office PC's (10.1.11.0, vlan 11) always want to route through the 172.16.140.0 wireless canopy. I can ping the main office ip's 192.168.0.252 (L3 fibre gateway) and 192.168.0.254 (main switch server gateway) from the remote location but the main office PC's on vlan 11 can ping the 192.168.0.254 server gateway but not the 192.168.0.252 fibre gateway.I've tried setting a static route on the remote switch to 10.1.71.0 via both 192.168.0.252 and 192.168.0.254 and then nothing works.I've tried static routes to 192.168.0.252 on the office side and nothing works.

If you have any suggestions it would be much appreciated. Or any more questions, please ask. Thanks.

Do some real traces yes, but we can play around with the network config ourselves with a packet tracer or GNS3 simulation file in our hands. The troubleshooting and diagram will help immensely as well instead of reading that wall of text. Particularly with the VLANs.
